10 Claims. (Cl. 242-130) This invention relates to bobbin holders or thelike for use in textile machines.

An object of the present invention is to provide a bobbin holderarrangement including a set of interchangeable adaptors, whicharrangement may be used for a great variety of bobbins of dilferentshape and type, for example, rayon cones, cotton cones, pineapplepackages, nylon pirns, etc.

A further. object of the invention is to provide a bobbin holder whichmay be readily used in conjunction with different kinds of adaptors forvarious types of bobbins or yarn packages.

Another object of the present invention is -to provide a bobbin holderof such construction that its radius of swinging about the axis of aholding rod is reduced to a minimum, so that if bobbin holders accordingto the invention are used in conjunction with a creel, the distancebetween the holding rods of the creel and, consequently, the overalllength of the creel, can be held to a minimum.

A further object of the invention is to provide a bobbin holder whichpermits an easy and effective attachment of a holder carrying a pad "ofsheepskin or the like.

Another object of the invention is to provide an adaptor for use inconjunction with a bobbin holder, which adaptor is capable of receivingcones of different taper.

Still a further object of the present invention is to improve on theconstruction of bobbin holders and bobbin holder arrangements as nowcustomarily made.

Other objects and structural details of the invention will be apparentfrom the following description when read in conjunction with theaccompanying drawings forming part of this specication, wherein:

Referring now to Figs. 1-5, 20 indicates a holding rod pertaining to atextile machine, for example, a creel.

A set collar 22 slid over the holding rod 20, and arranged between theforked ends 24 of an arm 26 of the bobbin holder is held in its positionby means of a set screw 28. Each of the forked ends 24 has a bore 30rotatably engaged with the holding rod 20. The free end of a spring 32(see Figs. 3 and 5) secured to the arm 26 by a screw 33 may come intooperative engagement with a recess 34 of the set collar 22 for holdingthe swingable arm 26 in a predetermined position.

As best shown in Figs. l and 5, the other end 36 of the arm 26 is oisetrelative to the center C of the bores of the forked ends of the arm.This ofset end 36 carries a boss 38 of conical shape, and is providedwith a bore 40.

One end of a shank 42 is inserted into the bore 40 of the boss 38, andis iixedly secured thereto.

As best shown in Fig. 2, the shank 42 is provided at opposite sides withlongitudinal slots 44 communicating with each other by a bore 46. Thecrown of a wire spring generally indicated by 48 is inserted into thisbore 46, the legs of this wire spring extending longitudinally from theshank 42 on opposite sides thereof. Each leg of the spring 48 has twobowed portions 50 and 52 adjacent each other. The bow 52 is somewhatlarger than the bow 50. The portion of the spring 48 between these twobows 50 and 52, as well as the free end of each leg of the spring, isslidably engaged with the slot 44 of the shank 42. Upon compression ofone or both bowed portions of each leg of the spring 48, the free end ofthe leg slides along the associated slot 44 to the left, as viewed inFig. 2.

Furthermore, the free end portion of the shank 42 is provided with atrst circular groove 54, and a second circular groove 56, the latterbeing narrower than the former.

As shown in Figs. l, 3 and 5, the end 36 of the arm 26 is provided witha lug S8 for purposes to be described further below in detail.

The above described bobbin holder, comprising the arm 26 and the shank42 provided with the double-bowed wire spring 48 may be used forcarrying a bobbin or the like directly or through the medium of anadaptor placed on the shank 42.

According to the arrangement shown in Fig. 1, a spacing element 60having a center bore 62 and diametrically opposite longitudinal grooves64 (see also Fig. 4) is placed on the shank 42 in such a manner that thebowed portions 50 of the wire spring 48 come into engagement with theselongitudinal grooves 64, whereby the spacing element 60 is held in acertain position. The bowed portions 50 engaged with the longitudinalgrooves 64 prevent the spacing element 60 from rotation. The spacing element 60 may be made of wood or any other suitable material.

Upon attachment of the spacing element 60, an adaptor, generallyindicated by 66, and provided with a center bore 68 is placed on theshank 42. Due to the small diameter of the center bore 68, the bowedportions 52 of the wire spring 48 are compressed, the latter tending tohold the adaptor 66 in place.

Preferably, a snap ring 70 is engaged with the circular groove 56 of theshank 42 so as to prevent the adaptor 66 from axial displacement. Theadaptor may be made of wood, or other suitable material, for example, aplastic.

The adaptor 66 comprises two portions 72 and 74 of conical shape, thetaper of the portion 72 however, being of a lesser degree than the taperof the portion 74. Furthermore, the conical portion 72 is provided withan annular groove 76.

According to the arrangement shown in Fig. l, the core 78 of a rayoncone 80 is engaged with the conical portion 72 of the adaptor 66.

If a bobbin holder is used in a creel, it is necessary to swing the arm26 carrying the shank 42 around the holding rod 20 for loading of thebobbin holder with a bobbin or the like, or for the removal of an emptycore.

As will be readily understood from an inspection of Fig. 5, the swingingradius r caused by the distance between the center C and the end of theshank 42 is smaller than it would be were the end 36 of the arm 26 notoffset relative to the center C. Consequently, it is possible to reducethe distance between two adjacent hold ing rods in a creel, with theresult that the overall length of a creel may be considerably lessened.

Fig. 6 illustrates a different use of the bobbin holder arrangementshown in Fig. l. The same spacing element 60 and the same adaptor 66 areapplied to the shank 42 carried by the arm 26 mounted on the holding rod20. ,However, a ring-shaped coil spring, or garter spring 82 is insertedinto the groove 76 of the adaptor 66,

so that the latter may safely carry the core 84 of a cotton cone 86. Theconical core 84 of the cone 86 having a higher degree of taper than theconical core 78 of the cone 80 shown in Fig. 1 is engaged with theportion 74 of the adaptor 66 and the garter spring 82, as shown in Fig.6.

Furthermore, according to Fig. 6, a holder 88 carrying a pad 90 ofsheepskin or the like for cooperation with the cone 86 is attached tothe spacing element 60 by Irdri'ears of screws, only one screw 92 beingshown in According to Fig. 7, instead of the spacing element 60 and theadaptor 66 described above, an adaptor 94 of the compressible cage type,substantially of the construction described in my Patent No. 2,437,100,is mounted on the shank 42 of the bobbin holder, according to theinvention. The adaptor 94 is held in its position by means of a setscrew 96 engaged with the circular groove 54 of the shank 42. The base98 of the compressible cage type adaptor 94 is in engagement with thebowed portions 52 of the wire spring 48 of the shank 42. Thecompressible cage type adaptor 94 may be used for carrying a rayon orcotton cone.

According to the embodiment shown in Fig. 8, the spacing element 60carrying a holder 88 provided with a pad 90 of sheepskin is mounted onthe shank 42 of the bobbin holder, in addition to the cage type adaptor94.

According to Fig. 9, the bobbin holder is made ready for carrying aso-called pineapple package 100. Again the spacing element 60 and theconical adaptor 66 described above in connnection with Fig. l aremounted on the shank 42 carried by the arm 26 of the bobbin holder. Thecore 102 of the pineapple package is engaged with the conical portion 72of the adaptor 66. A holder 104 carrying a pad 106 of sheepskin isattached to the spacing element 6i). The holder 104 and pad 106 areshaped so as to suit the form of the pineapple cone 100.

According to Fig l0, the bobbin holder comprising the arm 26 and theshank 42 attached thereto is used for carrying a nylon pirn 108. Thispirn 108 has a cylindrical core 110, so that it becomes unnecessary toapply an adaptor to the shank 42. The end wall 112 of the core 110 isprovided with an opening 114 engaged with the conical boss 38 of the arm26.

Furthermore, the center wall of the core 110 is engaged with the bowedportions 52 of the wire spring 48. Thus, by the engagement of theopening 114 with the boss 38, and the inner wall of the core 110 withthe bowed portions 52 of the spring 48, the pirn 108 is safely held inposition. Too, the bent resilient end of a holder 116 carrying a pad 118of sheepskin is clipped on the lug 58 arranged at the end 36 of the arm26.

It will be noted that the left hand end (as viewed in Fig. l) of thepirn 108 extends into the space formed between the boss 38, and the bentportion of the arm 26.

As will be understood from above, the bobbin holder according to theinvention may be readily used for a great variety of different types andshapes of bobbins or the like. The adaptors may be readily interchangedso as to accommodate a bobbin or the like of any desired type.
